论文摘要
对于高（角）分辨率电子反向衍射（HR-EBSD），选择参考衍射模式（EBSP0）显着影响计算出的应变和旋转图的精度。这种作用在塑料变形的人体中心和中心的立方延性金属（双链不锈钢中的铁液和奥斯丁岩晶粒）和脆性的单晶硅中证明了这种作用，这表明该作用不仅限于测量幅度，而且还限于空间分布。然后在互相关参数和角误差之间识别经验关系，该误差用于迭代算法中，以识别最大化HR-EBSD精度的最佳参考模式。
For high (angular) resolution electron backscatter diffraction (HR-EBSD), the selection of a reference diffraction pattern (EBSP0) significantly affects the precision of the calculated strain and rotation maps. This effect was demonstrated in plastically deformed body-centred cubic and face-centred cubic ductile metals (ferrite and austenite grains in duplex stainless steel) and brittle single-crystal silicon, which showed that the effect is not only limited to measurement magnitude but also spatial distribution. An empirical relationship was then identified between the cross-correlation parameter and angular error, which was used in an iterative algorithm to identify the optimal reference pattern that maximises the precision of HR-EBSD.
